Research and application of a novel deep profile modification agent for complex sandstone reservoirs
According to low temperature, high salinity, heterogeneous and complex sandstone oil reservoirs in the Qaidam Basin.A novel profile modification agent (PMA) was developed by the author.The microscopic structure of the agent was analyzed by SEM.The PMA of 0.3% has stronger plugging capacity to cores.Its blocking coefficient was larger than 91%, and it was not less than 90% after being flushed with 20PV injected water.In parallel core test the agent could be used to adjust the reservoir permeability and enhance oil recovery substantially.The field test achieved good results.
